WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 364,309, dated June 7, 1887.

(No model.)

To all 1071/0112 it may concern:

Be it known that I, LoUIs H. SHOLDER, of Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Window-Screens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

I My invention relates to improvements in window-screens in which the screen is attached to a spring-actuated roller that is mounted in a suitable casing, the latter being made to fit and slide between the windowstops. The casing has brackets with spring hooks attached for engaging latera'llyprojecting pins of the'lower sash, to the end that the hooks may be detached from the pins, leaving the screencasing resting on the window-sill while the sash is being raised, and that when .the sash is lowered the spring-hooks will antomatically engage the pins of the sash, after which engagement the screencasing is ele vated with the sash. The slat to which the bottom or free end of the screen is attached has spring-catches that engage suitable fastenings for holding the slat down next the wi11- dow-sill, to the end that the screen may be uni'astened and the screen raised with the sash without distending the same; or if the slat is left fastened the screen is distended by raising the sash. The slat having been unfastened when the sash is lowered, the spring-catches automatically engage the aforesaid fasteners. The hooks of the screen-case and the catches of the screen-slat having been unfastencd by tilting the screen-casing, it is easilyremoved from between the window'stops and as easily returned to its place.

My invention also relates to details of con struction, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an outside elevation of a window having my improved screen attached, the sash being partly raised andthe screen being correspondingly distended. Fig. 2 is an outside view showing the sash raised and the screen left on the windowsill. Fig. 3 is an inside elevation showing the sash raised and the screen detached. Fig. 4 is an end elevation on the line of x as, Fig. 1.

Fig. 5 is a side elevation,

Figs. 7, S, and 9 are details illustrating the construction of the screen mechanism, and hereinafter more fully described. Fig. 10 is an elevation in transverse section showing the central portion of the sash and screen. Figs. 11 and 12 are respectively an elevation and plan of the screen slat and fastening. Figs. 13 and 14 are respectively a plan and side elevation of the wedgeshap'ed cam G.

A represents the lower sash, having later- For convenience, common wood-screws may serve for these pins, and when used are screwed into the sash, leaving the shank and head of the The upper and lower sash slide between stops A, arranged in the usual A suitable casing, 13, usually of galvanized iron, is made of suitable length to extend across the window and of suitable width to enter and slide easily between the windowstops, the casing being placed between the stops of either the upper sash or lower sash,

according as the screen is secured underneath or outside of the lower sash; but we will supposethe screen located in the latter position, as shown in dotted lines in Fig. 4.

The casing 13 has brackets B, located near the ends of the casing and on the inner side thereof; The bracketshave depending arms that abut the outside of the lower sash, by which engagement the casingis held from rocking and consequent binding between the stops. To the brackets are pivoted the springhooks b, that engage the aforesaid pins a of the sash when the parts are in working position. The hooks have inclines, as shown, by reason of which the hooks are snubbed back in passing the pins and automatically fastened to thepins when the parts are in position. i

The casing B, when placed outside of the lower sash, as shown by full lines, Fig. 4, is separated from the latter the thickness of the stops A. An apron, B, is secured usually to the casing, and extends to the sash to close this space. In place of such apron an ordinary weather-stri p might be secured to the sash, if preferred. A spring-roller, G, is mounted in free or bottom end thereof.

. the trunnion revolves in operating the device.

which by pressing the trunnion 0 back into the casing, on which roller is wound the screen I D, the latter having a slat, E, attached to the This slat has a spring-catch, E, the points of which engage screw-eyes F, or other suitable fastenings, to hold the slat down to the window sill. The spring catch is preferably made of a single rod bent substantially in the form shown in Figs. 11 and 12, the same having a loop or thumbpiece, 6, and beveled ends 6 and an actuatingspring, F for moving the catch endwise to engage the fastening. In lowering the slat, the catch E is snubbed back in passing the fastening F and made to hook under the fastening by the action of the spring E. The slat E has pins or lugs 0 extending from the ends thereof that engage notches b of the end walls of the casing B, by which engagement the slat is accurately held in place, so that the catches E are brought in position to engage the fast eniug F. I

The construction of the spring roller 0 is more clearly shown in Figs. 5 and S. Oneof the end plates, I)", of the casing B has a square or rectangular hole, I)", in which hole is placed the flattened end a of the spindle c, the other end ofthe spindle beingjournaled in a head, 0", inside the roller. To'the spindle is attached the one end of the coil-spring G, the other end of the spring being secured to the casing, the arrangement ofparts being such that the spring is coiled by unwinding the screen, and consequently the recoil of the spring turns the roll in the direction to wind up the screen. The opposite end of the roller has a socket, in which is placed the trunnion 0*, said trunnion being backed by a spring, 0", at the rear end of the trunnion.

In assembling the parts the end 0 of the spindle is first placed in the hole I), after its socket the roller is easily inserted into the casing, after which the trunnion by the action of the spring is forced out so as to engage the hole in the end of the casing, in which hole The windowsash, when raised, must have some fastening to hold the sash against the downward draft of the screen caused by the tension of the roller-spring, and it is desirable to have such fastening connected with the screen-casing, so that the entire device may be placed in position or removed together. I have therefore devised the following: The depending arm of the bracket B stands out from the casing B, as shown in Fig. 6, and between the depending arm and the body of the casing and pivoted to the latter is a cam, G, having a thin edge, so that in cross section the cam is wedge-shaped. The cam has a small thumb-lever, g, for operating the same. Vhen the sash is raised, by moving the lever g with the fingers the edge of the cam is made to enter between the casing B and the adjacent window-stop, and in this mannerholds the sash from descending.

If preferred, the casing 13 may beset under the lower sash, (see dotted lines, Figs. 4 and 10,) in which case the bracketsdZ will be on the inside of the sash, as will also be the pins a, and the casing B will be of course between the stops of the lower sash, and the fastening F will be arranged accordingly. Of course it is not intendedto move the screen from the one position to the other, and it is attached to the outside of the sash or underneath the sash, whichever is preferred, and thenleft in such position. If it is applied underneath the sash, of course the apron B will not he wanted.

In operating the device, by pressing back the hooks b with the fingers, to do which, if the screen is on the outside of the sash, the sash must be raised a trifle to make the hooks accessible, the sash may be raised and the screeneasingleft 011 the window-sill-as, for instance, in cleaning the sash or for other purposes-after which by lowering the sash the hooks automatically couple the casing to the sash. Now by unfastening the catch E and raising the sash the entire device is carried up with the latter, leaving the window-sill free to be cleaned. By unfastening both the hooks and the catches and tilting the casing B a trifle it may be removed entirely from the window.

What I claim is 1; The combination, with a window-screen casing having a roller, substantially as indt cated, of a spring-fastening for automatically securing the casing to the window-sash, substantially as set forth.

2. The combination, with a casing having notches in its ends, springcatches for automatically securing the casing to a windowsash, a spring-roller mounted in said casing, and a screen secured to said roller, of a slat secured to the lower end of the screen and provided with spring-catches for removably securingit to the window-sill and with projecting lugs, substantially as set forth.

In testimony whereof-I sign thisspecification, in the presence of two witnesses, this 27th day of April, 1886.

LOUIS H. SHOLDER.
